Abstract

The invention relates to a process for preparing polymeric particles, comprising polymerized units of methacrylic acid and further monomers, with an overall monomer composition by weight comprising polymerized units of 5 to 25 % by weight methacrylic acid and 75 to 95 % by weight of further monomers, wherein the further monomers are selected from C1- to C4-alkylesters of methacrylic acid and/or C1- to C4-alkylesters of acrylic acid, by stepwise or gradient emulsion polymerization, wherein the ratio by weight of polymerized units of methacrylic acid to further monomers is increasing stepwise or in a gradient from the center to the surface of the particles and wherein the polymeric particles are obtained in the form of an aqueous dispersion.
